Answer:
The Earth has different compositional and mechanical layers. Compositional layers are determined by their components, while mechanical layers are determined by their physical properties. The outermost solid layer of a rocky planet or natural satellite. ... The Earth has an outer core (liquid) and an inner core (solid).

Answer:
If two plates move away from each other then a continental rift will form.
Explanation:
There are three basic types of plate boundaries, convergent, divergent, and transform plate boundaries. All of them have their own characteristics and the boundaries can be between oceanic and oceanic, oceanic and continental, and continental and continental plates, and each type creates different landforms.
If there are two plates moving each other over land, then a continental rift will form. Basically, the two plates slowly move away from each other, opening a gap that is constantly widening, so over time, it grows into a rift valley. Over the course of millions of years, the continental rift or rift valley will get filled by oceanic water and physically separate the two landmasses. A perfect example of this is the divergent plate boundary between the Nubian and Somali plates which have created the rift valley cutting through the eastern part of Africa.

Answer:
Water and the chemicals it contains are constantly being exchanged between the land surface and the subsurface. Surface water seeps into the ground and recharges the underlying aquifer—groundwater discharges to the surface and supplies the stream with baseflow.
Explanation:
Well, I am a Muslim, (a person in the religion of Islam), so I could answer this very easily.
Why it's so important to North African countries is because North African Countries are closer to the middle east; the "base" or "home" of Islam.
Why you may ask is it our base/home?
Well that's the area of land our religion was founded in, by our Prophet Muhammad (May peace and blessings be upon him).
So, since North African Countries are very close to the middle east, (they actually used to be part of the middle east; in fact, all countries were actually one full piece of land called "Pangaea" until Earth's tectonic plates divided it into multiple pieces of land), they felt as if they would interpret many of the middle east's customs, religion, tradition, culture, and basically their lifestyle.
This is why it's important :)
I hope I helped you! ^-^
